  • GnRH
  • We analyzed the predictive factors for oocyte retrieval failure following controlled ovarian hyperstimulation (COH) with gonadotropin-releasing hormone (GnRH) agonist and GnRH antagonist protocols in ART programs. (biomedcentral.com)
  • Controlled ovarian hyperstimulation (COH) which combining GnRH antagonist co-treatment and GnRH agonist trigger with an additional 1500 IU hCG luteal rescue on day of oocytes retrieval, has become a common tool aiming to reduce severe ovarian hyperstimulation syndrome (OHSS).

  • fentanyl
  • The aim of this study was to compare the addition of intravaginal local anaesthetic injection versus saline placebo to our usual analgesia regime to see whether less intravenous fentanyl was required and whether the women experienced less pain during oocyte collection. (clinicaltrials.gov)
  • concentrations
  • Table 1 gives an overview of the mean number of days of stimulation, the mean of the total number of ampoules of FSH used during the stimulation, the mean of the final E2 concentrations before oocyte retrieval , and the mean of the daily percent E2 increase. (thefreedictionary.com)
  • semen
  • In experiment 4: The matured oocytes were fertilized using fresh and frozen thawed semen. (ul.ac.za)
  • 0.05) number of 2-4 cell, morula and blastocyst when compared with oocytes that were fertilized using fresh semen. (ul.ac.za)
  • The retrieval can be also performed outside of our facility - it is necessary to obtain a sterile container and information about correct manipulation with the collected semen from the andrology laboratory. (sanatorium-helios.com)
  • technique
  • Polar body biopsy (PBB) is a common technique in preimplantation genetic testing (PGT) to assess the chromosomal status of the oocyte. (springer.com)
  • All collected mature excess oocytes were cryopreserved using the vitrification technique. (biomedsearch.com)
  • different
  • Among the different methods, polar body biopsy (PBB) has evolved to a common and secure method for infertile couples to assess the chromosomal status of the oocyte. (springer.com)
